Linear attenuation coefficient of different phases in soil and the corresponding greyscale histogram. (a) Linear attenuation coefficients of air, water, quartz, and potassium iodide at X-ray energies from 1 to 1000 keV (data from [45] and the online FFAST database of the National Institute of Standards and Technology, USA). (b) Greyscale histogram of an undisturbed loess (from [46]). (c) Greyscale histogram of a compacted sand (from [9]).
